CONCRETE PAVING STONES FOR PAVING AREAS

Description

The invention relates to a concrete paving stone for paving surfaces as a cuboid stone or of any shape with vertical, preferably trapezoidal interlockings distributed over its surface, which begin below the paving stone surface and end at the foot level, with one or more deep dummy joints in the paving stone surface to accommodate filling sand.

The purpose of paving surfaces is to secure a surface in such a way that the loads caused by use are absorbed in such a way that no shifting, settling or even bursting of the paving stone surface occurs.

It should drain rainwater quickly through its joints into the substructure, so that optimal use is guaranteed even when it rains. It should also be formally convincing and thus meet the requirements of modern architecture.

Especially in the case of paved surfaces that are used for traffic, the horizontal thrust caused by the impact of traffic must be absorbed in the road surface; the rapid drainage of surface water is equally important in order to avoid the risk of aquaplaning.

It 4 * *

It is known that rectangular stones of different formats are used for paving areas.

To make laying easier, the paving stones have joint spacers that allow for evenly wide joints across the entire pilaster surface, allowing surface water to drain away easily.
However, since these rectangular particles do not have a composite effect,

They cannot be used on heavily used surfaces.

Furthermore, a paving stone is known from European patent specification 0 060, the lower part of which has vertical serrations distributed over its surface, which are intended to ensure good anchoring of the stones among each other.
The circumferential interlocking ensures that the stones are firmly anchored to one another, but the resulting minimal amount of joints in a paving stone surface only allows surface water to seep through to a limited extent and there is a risk of aquaplaning. The applicant is also aware of a paving stone in which a system of deep grooves and tongues is connected directly to the ashlar stone, thus leading to a force-locking connection between the paving stones laid. Good water drainage is not achievable here either. In large-format paving stones in particular, the amount of joints becomes smaller and smaller, which further hinders water drainage.

It is also known that paving stones have dummy joints which, when filled with sand, give the impression of individual stones.

The apparent joint height of these mostly large-format paving stones is the same everywhere.

Any surface water that accumulates can therefore only be drained away via the actual joint between paving stones. In the cold season, there is a risk of frost damage in the dummy joints due to poor water drainage.

The invention is based on the task of developing a large-format concrete paving stone that, when laid, guarantees good surface water drainage into the substructure.

It should also guarantee a strong anchoring of the stones to one another. It should also have one or more dummy joints that guarantee a variety of designs for the paving surface and support water drainage.

This object is achieved with a paving stone as described in the claims.

The invention will now be explained in more detail with reference to the drawings.

Summary

CONCRETE PAVING STONES FOR PAVING AREAS

The invention relates to a concrete paving stone for paving areas as a cuboid stone or of any shape with vertical, preferably trapezoidal, toothing distributed over its almond surface, which begins below the paving stone surface and ends at the foot level.

It has one or more deep dummy joints in the paving stone surface (3) to accommodate filling sand.

The essence of the invention is that at the exit points of the dummy joints on the paving stone edge, the teeth are spaced wider on the mandrel surface and the vertical teeth are left out in some areas.

A further design requires that the dummy joint has a gradient either starting from the middle and ending at the edge of the concrete paving stone or starting from one edge of the concrete paving stone and ending at the other edge of the concrete paving stone.

The main advantages are that a large-format paving stone guarantees good surface water drainage into the substructure when laid and at the same time achieves a force-locking anchoring of the stones among each other.
